Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 18 "long-term" acoustic monitoring stations on 12 Hawaii Army National Guard (HIARNG) installations across the islands of Hawaii, Maui, Molokai, Oahu, and Kauai between 2012 and 2018. Hawaiian hoary bat insect prey sampling with paired acoustic monitoring was conducted at Keaukaha Military Reservation (KMR) on Hawaii Island from May to August, 2018. At this property, a herd of domestic goats (occasionally mixed with domestic sheep) were rotated among grazing plots as part of a weed control program managed by HIARNG. We sampled insect abundance and community within the area where goats were used for...
We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Honōkohau National Historical Park located in the coastal region of Kailua-Kona, Hawai‘i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1 and 10 m above sea level, that operated nightly from November 2013 through February 2015. This data set includes data derived from these acoustic recording stations. Each acoustic recording station was comprised of an acoustic recording unit (SM2Bat+ Song Meter Digital...

Waihou Mitigation Area, Maui Island, bat acoustic activity, diet and prey availability, 2015 to 2018
Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae) were examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu'u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. The study was conducted to inform the mitigation and management requirements of Auwahi Wind Energy, and fulfill requirements for mitigating bat fatalities under its approved incidental take permit. Acoustic monitoring over the three-year period demonstrated that bats are present and actively feed year-round at the Waihou Mitigation Area. This study included the first genetic analysis of Hawaiian hoary bat...
We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Honōkohau National Historical Park located in the coastal region of Kailua-Kona, Hawai‘i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations (KAHO1-KAHO7) between 1 and 10 m above sea level, that operated nightly from November 2013 through February 2015. Nocturnal aerial insect collection occurred in January and April (2 or 3 nights each) and in July and November (1 or 2 nights each) in 2014. Insects were collected...
Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 18 “long-term” acoustic monitoring stations on 12 Hawaii Army National Guard (HIARNG) installations across the islands of Hawaii, Maui, Molokai, Oahu, and Kauai between 2012 and 2018. Bats were confirmed as present at 10 of these installations: Kealakekua Armory, Keaukaha Military Reservation (KMR), Hanapepe Armory, Kekaha Firing Range (KFR), Puunene Training Facility, Ukumehame Firing Range (UFR), Kaunakakai Armory, Bellows Regional Training Institute, Kalaeloa, Barber’s Point, and the 487th Military Parking Facility, Wahiawā. Our acoustic sampling did not record bat vocalizations at Fort Ruger and...
Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae), was examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu‘u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. Research funding was provided by Auwahi Wind Energy, LLC (Auwahi Wind) to fulfill requirements for mitigating bat fatalities under its approved incidental take permit. The study was conducted to inform the mitigation and management requirements of Auwahi Wind Energy.
